Settings:

After the body tag, paste the following code:

<script src="/patch/to/slider.js"></script>
 <script>
     let slider = new Slider(".target", ['/patch/to/image'], { auto: {} });
 </script>

The last parameter when creating a slider is an object with settings.

At the moment the option auto:{} is required.

It has the following parameters:

auto: {
    active: false || true,
     timeout: 3500
}

timeout - ms.

Also, the settings object can look like this:

{
    duration: 600,
    auto: {
        active: false,
        timeout: 3500
    }
}

duration - The duration of the animation change slide, ms

auto.timeout - Slide change interval, ms

auto.active - Turn automatic slide change on or off, bool

The second parameter specifies an array with images

Look like this

[
    '/patch/to/image',
    '/patch/to/image2',
    '/patch/to/image3'
]
